Q:
# Which ordered pair is a solution for the system of equations? {3x−5y=152x−y=−4 (−5, −6) (0, 3) (2, 8) (−6, −11)

Accepted Solution

A:

3x-5y =15

2x-y=-4

multiply the equation by 5 and then subtract equation 2 from equation 1

so 3x-5y =15

10x-5y =-20

-7x =35 x =-5

plug in the value of x in the second equation -10 -y =-4 - y= -4 +10 y =-6

x=-5 y=-6

2x-y=-4

multiply the equation by 5 and then subtract equation 2 from equation 1

so 3x-5y =15

10x-5y =-20

-7x =35 x =-5

plug in the value of x in the second equation -10 -y =-4 - y= -4 +10 y =-6

x=-5 y=-6
